TO ALL WHOM IT MAY CONCERN:

Be it known that 1, JAMES L. SPENCER, of Wellville, in'the county ofNottaway, and btate of Virginia, have invented a new and useful ImprovedAdjustable Sulky-Plough and Tobacco-Hill Attachment; and I do herebydeclare the following to be a full, clear, and exact description of thesame, reference being bad to the accompanying drawings, forming part ofthis specification, and in which Figure 1 represents a horizontal planof my invention.

Figure 2 is a side elevation of the same.

Similar letters of reference indicate corresponding parts in the twofigures.

The'main features of this invention are the making of the axleadjustable in length, the method'employed in lifting the ploughs overobstructions, whereby any one plough may he lifted independently of theothers, or all may he lifted together, and the attachment fortobacco-hilling. .In the drawings- A A represent the sides of the frame,attached at their extremity to cross-beams BB 13 by-rneans of setscrewsand slots, or any equivalent arrangement, by which the width of'theframe may be readily adjusted. C G are bolts passing verticallythrough'the sides A A, between the cross-beams B B", into the lower endsof which are screwed lugs c c which support the bar D, to which theforward end of the plough-beams is attached. The bar D is square at oneend, where it is keyed or otherwise fastened in the lug. At the oppositeend it may be of any form. The plough-beam next to the pins that fastenthe bar D may approach very near the lug or hearing, but on the oppositeend a space must be left between the bearing and the plough-beam, inorder that the bar D maybereadily removed for any purpose. E E arethedraught-wheels working on F, an extensionaxle. The latter is thesimplest form of extensionwbeam, composed of two pieces overlapping andsliding longitudinally upon each other and united by metallic clasps ff,or by slots'and set-screws. These clasps have vertical sockets f intheir front sides, which. serve as guides and supports to the verticalhandlesgof the ploughs. G G G G: are ploughs attached by standards tothe plough-beams H H. The forward extremities of the latter are hingedto the bar D, and near their rear extremities they are provided withupright handles g.

At a point in thesides of the frame almost directly over the axle, postsI I are fixed, which support the square bar K. Upon the latter aresliding cars 7c 7c, in number corresponding with the ploughs. Behind theposts I I and bar K, working in sockets attached to the upper sideof theside pieces A A, is a roller, L, providedwith short arms I Z equal innumber to the ploughs, and situated directly below and behind the ears7c it. These arms are fixed in slots in the roller, so as to be adjustedto the position of the sliding ears 7c is.

A long handle, Z, is also attached to the roller L. It may be a separatepiece, or, as shown in the drawings, simply an extension of one of thearms ZZ. Pivoted on pins in the cars 70 here short arms M M, the forwardends of which are connected by lifting-chains to the plough-beams H H,directly in front of the point where the handles g are attached to theplough-beams, and the rear ends of which carry links m m, from whichhang vertical rods m m. These rods pass through links it n attached tothe outer extremity of the short arms I I. Just below the point wherethe rods pass through the links, the former are provided with stops 0 0which catch against the links and prevent the rods from being drawn upthrough the links any further than the point where the stops areattached. On the other hand, should the arms Z lbc depressed, the linksoperate on the stops 0 0 and depress the rear end of the arms M M,elevating the front end of these arms, and with them the ploughsattached to them. It is evident that if the handle Z be depressed, allthe ploughs will be raised, but if the rear end of any one of the arms MM be depressed, only the plough connected with that arm will be raised.

The ploughshares are made detachable from the standards which carrythem. I have used right-andleft ploughs in constructing my model, twowith mould-boards on the right, two with thesame parts on the left ofthe standard. As the ploughs are detachable they may be interchanged atpleasure, when any advantage will result from so doing.

The lower extremities of the vertical rods m m are a little above thelevel of the under side of the axle when the ploughs are working, andare bent forward in order that they may, if necessary, be hooked underthe axle when the ploughs are raised, and keep them in that situation.This completes the description of the plough.

The tobacco-billing attachment isconstructed as follows: A cog-wheel, P,is firmly attached to the'inner side of one of the draught-wheels, andgears into apinion on the extremity of a shaft, Q. The pinion g slidesback and forth upon the end of the shaft Q. It is prevented from turningon the shaft by flutings or keys on the one working in correspondinggrooves or notches in the other. When the pinion is at the extremity oftheshaft it gears into the wheel P, but when it is slid back from theend of the shaft it disconnects from the wheel P, and is no longeroperated by it. It is thrown into and out of gear by means of the leverR. When the tobacco-.hiller is working, the rod 1 attached to the end ofthe lever may be hooked to the piece r on the rear cross-beam of theframe. The shaft Q bears at its centre, firmly attached to it, a wheel,S, projecting from the sideof which are three or more pins. Directlybehind this wheel, pivoted in ears depending fr omthe rear cross-beam,is a pole, T, an-arm of which projects forward alongside of the wheel S,tripping upon the pins on its side as the wheel revolves. The pole T hasshovel t attached, and a blunt arm, t, at just such a distance apartthat when! the shovel t shall have made the tobacco hill atone descentof the pole T, the next descent of the pole will cause the blunt arm tto strike the ground upon the hill thus made, and thus properly form thehill to receive the plant. This may easily be efi'ected by adjusting theposition of'the shovel and the blunt arm on the pole T proportionatelyto the distances between the pins on the side of the wheel S. U is ahand lever by which the pole T may be raised when necessary, and whendesirable to do so the forward end of the lever U may be fastened downby a link and pin, or other suitable device, similar to that used forholding the pinion-wheel g in gear. The shovel t and the blunt arm 1."may be fixed immovably to the tripping-pole T, or they may be made toslide on the pole T, and be adjusted thereon by set-screws or otherwise.Instead of one pole T bearing both theshovel and the blunt arm, twotripping-poles may be employed, one bearing the shovel t and the otherthe blunt arm t.

A machine thus constructed will admit of a guano-sower, seed-sower, orcorn-planter being attached. It is only necessary to fix the sced-box orguano-box between the beams B B and the lifting-chains. The shaft Q maybe taken oif and attached in front o the drive-wheels, so as to work asan agitator, the wheel S with its side pins being admirably adapted forthat purpose. The pins may strike directly against the seed-holder, orthe shaft Q may bear a crank and pitanan'attached to the seed-holder.

The sliding ears it kmay have set-screws to fix them at any point on thebar K. Instead of the arms MM, pulleys attached to the ears k is may beemployed. Set-screws may be also used in the bands that unite the twoparts of the axle-tree, if deemed necessary. 7

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is'

1. The combination and arrangement of the ploughs G G G G with the armsM M, the rodsm m, and the arms Z Z, substantially as and for the purposespecified.

2. The roller L, having the short arms lladjustable in position, andhaving the handle I, substantially as and for the purpose described. I I

3. The pole T, having the shovel t and blunt arm t, substantially as andfor the purpose specified.

4. The combination of the gear-wheel P, the pinion g, the lever B, theshaft Q bearing the wheel S, and the pivoted pole T'bearing the shovel tand the blunt arm t, substantially as andjfor the purpose described- Tothe above specification of my improvement I have signed my hand this16th day of May, 1867."
